mtg cards like eternal witness [286] [Commander Masters] [Foil] – Face to Face Games you may return target card from your graveyard to your hand Eternal Witness (Card) | EDHREC

Id consider it non-canon from a perspective of cards that are printed, but I think we can agree that its canon if anybody wants to consider it so for the convenience of entertainment

Spirits and other arcane spells are the best payoffs here

Back in the days, people played without sleeves and many of these old cards weren't stored properly

When you factor in the addition of more and more relevant flash cards, with Reprieve and Cathar Commando headlining recent printings, theres a lot to like here

Its a great artifact thats used in basically any control or midrange Commander deck
